Abstract: A wastewater treatment system is a septic tank adjacent to an aeration chamber. The aeration chamber has a tertiary baffle and a circular current of fluid wherein the circular current produces a down flow current of liquid past the tertiary baffle. This current prevents suspended particles from passing through the tertiary baffle.

Abstract: The present invention is a wastewater treatment system utilizing a recirculating filter system comprising sand, gravel, or synthetic media. Septic effluent is continuously, or approximately continuously, dosed under pressure to the treatment media through pressure compensating drip irrigation emitters. The dosed effluent is treated and dispersed into a dispersal field using double coiled distribution lines that can alternate flow through emitters to rest the dispersal field. The double coil dispersal lines allow more emitters per unit area allowing treatment of the effluent more slowly and effectively.

Abstract: The present invention is a wastewater treatment system utilizing a recirculating filter system comprising sand, gravel, or synthetic media. Septic effluent is continuously, or approximately continuously, dosed under pressure to the treatment media through pressure compensating drip irrigation emitters. The system comprises a commonly known septic tank and recirculation tank. Septic tank effluent is collected in the recirculation tank, from which it is continually dosed by means of a pump to the top of the treatment media of the recirculating filter through pressure compensating drip emitters. Continuous dosing of diluted residential septic tank effluent through drip irrigation emitters provides a slow consistent application of liquid rich in organic material and pathogens over the treatment media. The treated effluent is then recirculated if water is low or went to final disposal.

Abstract: The LoweFlow Filter wastewater treatment system is a recirculating filtering system intended to treat typical residential septic tank effluent. Septic effluent is continuously (or near continuously) dosed under pressure to the treatment media through pressure compensating drip irrigation emitters. Wastewater trickles down through the media where it is attenuated through physical, chemical, and biological means. Treated wastewater or filtrate collected from the bottom of the recirculating filter returns to the recirculating tank, either by gravity flow or under pressure, through the flow splitter. During periods of low or no wastewater flow, a flow splitter will allow all of the filtrate from the treatment filter back into the recirculation tank. During periods of moderate or high wastewater flow, the flow splitter will allow all or a portion of the filtrate to be diverted for final disposal.
